Inventor: HAYASHI HAJIME
IPC: G01R33/025
Filed: 1990-01-18
Abstract: An apparatus is provided for measuring a very weak magnetic field generated by a human body, etc. External magnetic noise components coming from other magnetic sources and existing around an object whose magnetic field is to be measured are detected by compensation coils (11, 12, 13) of the apparatus. The compensation coils are oriented in multiple dimensional directions. The detected noise components are weighted and added to each other to correctly find the noise components. Thereafter, the noise components mixed in the objective very weak magnetic field are removed, thereby correctly measuring the very weak magnetic field.

Abstract: A fluid flow control for use with a process chamber (22,22′). In the disclosed embodiment, the process chamber is for ion implantation of a workpiece and the fluid flow control is to assure the flow rates are maintained at values which are efficient in evacuating and pressurizing the chamber but are not high enough to dislodge particulate contaminants from the process chamber walls. In the disclosed design, the invention has utility both in instances in which wafers are directly inserted into the process chamber (22′) for ion implantation and in which the wafers are inserted into the chamber by use of a load-lock (72) which avoids the requirement that the process chamber be cyclically pressurized and depressurized.

Abstract: This invention provides an acoustic vibrational material containing various fibres as the reinforcement material and having an epoxy resin as a matrix resin, wherein the epoxy resin is modified by a polybutadiene base elastomer containing not less than 90 mole percent of 1, 2-­linked units. The epoxy resin modified with the above polybutadiene elastomer exhibits a maximum value of loss coefficient in the temperature region near room temperature. This region is much higher than that of the conventional epoxy resin modified with polybutadiene elastomer mainly including 1, 4-linked unit. Decrease in elastic modulus of the epoxy resin with increase of temperature is reducer in the epoxy resin of the present invention, whereas it is larger in the conventional one. Thus compatibility between large internal loss and high elastic modulus is achieved.

Abstract: The present invention relates to photosensitive compounds, more particularly polymers containing halomethyl-1,3,5-triazine moieties and to radiation-sensitive compositions and elements utilizing these polymers. Migration typically occurs in photopolymerizable compositions containing low molecular weight monomers and plasticizers, which tend to diffuse between layers, carrying along other ingredients such as the photoinitiator. This invention provides radiation-sensitive organo-halogen compounds that have a photo-labile halomethyl-1,3,5-triazine moiety and a polymeric moiety within the same molecule. The compounds of this invention are comprised of a polymeric moiety having attached or incorporated within its structure at least one 1,3,5-triazine nucleus, said triazine nucleus having at least one halomethyl substituent attached to a carbon atom of the triazine nucleus. These compounds are capable of being stimulated by actinic radiation at wavelengths of from about 250 to about 900 nanometers to generate free radicals and/or acids. The compounds of this invention are useful as photoinitiators in free radical polymerization reactions, oxidation-reduction reactions, or reactions sensitive to acid, and they also exhibit the capability to crosslink upon exposure to light. The polymers of this invention are less susceptible to migration on account of the anchoring or ballasting of the halomethyl-1,3,5-triazine.

Abstract: In a discharge excitation gas laser device such as an excimer laser device provided with laser medium gas (11) and a pair of electrodes (2a, 2b) opposite to each other in a gas-tight vessel (1), the laser medium gas is discharge-excited while inverting the polarity of a DC pulse voltage applied to the pair of electrodes opposite to each other for every pulse. In this way distribution of atoms and ions constituting the laser medium gas in the discharge region including the neighborhood of the main electrodes is made uniform even at a high repetition rate oscillation. Thus it is possible to realize a discharge excitation gas laser device having a good stability of DC pulse discharge without increasing unnecessarily the flow speed of the laser medium gas and no lowering in the pulse energy owing to a high efficiency operation.

Abstract: 2.1 In track jumping, when the scanning device of a playback apparatus travels rapidly over many data tracks of a disc, it is possible to jump accurately to just one track. However, in the worst case, it is necessary to wait for one revolution of the disc (CD) before the target point on the target track is sensed by the light beam of the scanning device. In the case of a CD player, a CLV system, this additional waiting time is 120 ms to 330 ms. 2.2 In order to reduce the access time, the speed of the disc which is required in order to sense the target point (P2) when the target track (S2) is reached is calculated from the number A of tracks lying between the data track (S1) last scanned and the target track (S2), from the angular positions of the point (P1) last scanned on the data track (S1) last scanned and the target point (P2) on the target track (S2) as well as from the duration of the jumping time. 2.3 Playback apparatuses and/or recording apparatuses which contactlessly scan a rotating disc, for example CD players, video disc players, DRAW disc players or magneto-optical equipment. <IMAGE>
